The Vmux-110 remote voice trunking gateway is a customer-located
device that complements the Vmux system, providing LAN and compressed
voice transmission over both TDM and Ethernet-based networks. Employing
powerful voice compression algorithms as well as TDMoIP technology, the
Vmux-2100 can compress a full E1/T1 or 4 or 8 analog lines, leaving more
bandwidth for data transport.
Voice compression reduces line costs
Vmux-110
remote site voice trunking gateway compresses voice traffic and
transports it over an n x 64 kbps, E1/T1 or IP link. The device employs
G.723.1, G.729 Annex A and G.711 compression algorithms together with
RAD’s unique TDMoIP multiplexing, and is transparent to all signaling
protocols and LAN.
Silence suppression improves bandwidth utilization
Voice
activity detection and silence suppression allow these Vmux units to
dynamically allocate bandwidth for voice traffic. This results in very
efficient bandwidth usage, leaving more bandwidth for data transport,
further controlled with rate limiting capabilities.
Ethernet port for data
For
data connectivity, the customer-located Vmux-110 features a second
10/100 BaseT port and an Ethernet switch for integrating the user LAN
traffic with the compressed voice over an IP, serial or E1/T1 uplink.
The Vmux-110 is a compact, 1U-high, half 19-inch wide unit that can be
mounted in a 19" rack. It supports four or eight FXS/FXO/E&M ports
or a single full or fractional E1/T1 voice port. The unit is available
with either an AC or DC power supply.
